I had a great experience at this dealership when I got my new Hummer EV. From start to finish, the process was fast, smooth, and surprisingly enjoyable. I spent time looking at a variety of cars, and the tea new Hummer EV. From start to finish, the process was fast, smooth, and surprisingly enjoyable. I spent time looking at a variety of cars, and the team was incredibly patient while I explored my options—even when I ended up completely changing my mind and going with something I never expected, but now absolutely love. Not only did they get me exactly what I needed, when I needed it, but they also helped me get everything wrapped up in time to pick up my son from daycare—so the process was efficient and painless. JC was especially accommodating throughout the experience, and Sam worked hard to make sure the numbers fit within my budget. The follow-up and customer care after the sale have been excellent as well. I’m a happy customer and would recommend this dealership to anyone. More
